Abstract: TITLE      INTERLOCK WITH INSIDE OF CYLINDER      ABSTRACT      A cylinder, such as the barrel of a caulking cartridge, interlocks with an internal member, such as the closure plunger for the caulker, by means of two to four cuts through the cylinder wall evenly spaced from the end of the cylinder to form catches from the segments of the wall between each of the cuts in the end of the cylinder. The catches are longer circumferentially of the wall than their width from the cut to the end of the cyl-inder, and they are deformed inward from the locus of the cylindrical wall toward a chord orientation. The member has a body fitting the inside of the cylinder and slidable past the catches, and the body is seated inside the cylinder so the catches are disposed between the body and the end of the cylinder to interlock with the body to prevent its movement out of the end of the cylinder. The cuts and catches can be formed either before or after the member is seated in the cylinder, and the inward deformation of the catches to insure an interlock can be accomplished by the way the cuts are formed, or by an interference fit between the member and the cylinder, or both.

Abstract: ABSTRACT OF THE DISCLOSURE        A display device is disclosed which employs a magnetic panel.  The magnetic panel is formed by two oppositely arranged substrates at least one of which is transparent or semi-transparent.          The space between the two substrates is filled with a dispersing liquid having a yielding value higher than 5 dyne/cm2.  The dispersing liquid is prepared with fine magnetic grains, a colouring agent, a dispersing medium, and a fine grain thickener.          Preferably, a multi-cell structure is provided in the space between the two substrates and the substrates are sealed to the multi-cell structure to form a plurality of independent display cells.  A displaying magnet in the form of a pen is used to form a display by causing the fine magnetic grains to migrate to the front of the magnetic panel.  An erasing magnet is slidably disposed at the rear of the magnetic panel.

Abstract: ABSTRACT:           Disclosed is a picture display tube comprising an envelope having a display window, a cone and a neck.  An electrode system to generate at least one electron beam is mounted in the neck and an electrical resistive layer extends over an internal wall portion of the envelope to a point near the electrode system.  The tube comprises a getter which is detachably secured to a connecting member projecting internally from the wall of the tube at a location remote from the electrode system by means of a resilient connection strip,  The portion of the connection member projecting from the tube wall has a gradually widening end having a largest transverse dimension D and a smallest transverse dimension d and the connection strip of the getter has a first aperture whose dimensions are larger than the dimension D.  The first aperture debouches via a passage of width b into a second aperture of dimensions A in a manner such that D> A> b> d, so that the gradually widening end of the connecting member in cooperation with the second aperture forms a detachable coupling.

Abstract: CRUSTACEAN POT LINE COILER   Abstract A crustacean pot line coiler is disclosed that draws line from the primary huller block and utilizes the natural coiling tendency of twist-type synthetic pot lines to effect coiling of the line by feeding it downwardly into a receiving tub from a central elevated position. The line is thrust fed into the tub through the nip of opposing drive rollers, one of which is power driven and provided with a pneumatic tire to grip the line tractionally while allowing knots to pass at the high having velocity required without imposing undue mechanical shock on the system.  The other drive roller has a reentrant groove accommodating the line and also the power driven roller. Retractably mounted, the latter roller is yieldability pressed by a return spring against the power driven roller in a generally horizontal direction. A guide sheave overlying the nip of the drive rollers leads the line downwardly into the latter from a sufficient height above them as to form a laterally deflectable stretch of the line adjacent the drive roller nip. This contributes to the effectiveness of the pneumatically inflated drive roller tire and the horizontal yieldability of the opposing drive roller to pass knots with minimum shock to the system and minimum line dislodgement tendencies.

Abstract: MEANS CONNECTING CIRCUIT BREAKER AND AUXILIARY FEATURE MODULES                      ABSTRACT OF THE DISCLOSURE A single pole circuit breaker module is constructed so that its housing is provided with frangible sections aligned with the pivot pins for the Contact arm, the cradle and the operating mechanism latch.  These pins are keyed to the elements mounted thereon and each pin is provided with a formation to engage a complementary formation projecting sideways from an auxiliary feature module.  The latter includes one or more auxiliary devices. In the case of an auxiliary switch module, the switch thereof is connected to the contact arm pivot pin so that contact arm motion is transmitted to operate the auxiliary switch thereby indicating whether the circuit breaker is open or closed.  In the case of an alarm switch auxiliary module, the switch thereof is connected to the pivot pin for the cradle whereby the tripping of the cradle is effective to operate the alarm switch.  In the case of a shunt trip auxiliary module the solenoid operated member thereof is operatively connected to the pivot for the circuit breaker latch whereby actuation of the shunt trip solenoid serves to move the latch to its unlatched position for tripping of the circuit breaker.
